VALLE, Rubén, VALENCIA, Víctor y HUAMAN-MUNANTE, José. Neurofibromatosis tipo 1 asociado a tumor maligno de la vaina de nervio periférico y a carcinoma de colon. An. Fac. med., sep. 2009, vol.70, no.3, p.211-216. ISSN 1025-5583.

Neurofibromatosis type 1 is a dominant autosomal disease caused by mutation of the neurofibrin gene located in chromosome 17q11.2. This disease presents a variety of clinical manifestations and predisposition to develop tumors, leading to high mortality. We report the case of a patient with neurofibromatosis type 1 diagnosis who developed a malignant tumor of peripheral nerve sheath and colon cancer. The authors review the literature as well as the clinical factors, imaging and histological features associated to neurofibromas malignant transformation.
